PENCIL-PRINTlNG MACHINE.

Specification of Letters Patent.

atented April 23, 1907.

Application filed December 22,1905. Serial No. 292,959.

Amah and State of Oregon, have invented a new and useful Improved Pencil-Printing Machine, of which the following is a specification.

` hereinafter.

This invention relates to -a machine for printing pencils, the object being to provide a cheap, simple and ellcient construction of hand operative. machines, capable of quickly and easily imprinting one or more .lines upon a wooden lead pencil, the complete operation being completed at one movement of the machine, irrespective of the number of lines printed upon the pencil.

The. invention also has other objects in view, all of which are accomplished by the means herein shown and described, and pointed out in the claims.

' In-the drawings forming a part of this specification: Figure l is a top plan view of a pencil printing machine, constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the same, the dotted lilies showing the position of the parts at the completion of the printing operation. Fig. 3 is a top plan view of the bed-plate, and Fig. 4 is a detail perspective view showing one side of the hopper, the platen, the per'cil feeding rods, and a portion of the inking roll.

ln carryingr out my invention, I employ a bed-plate A, which may be of any suitable size desired and at the forward end thereof is reduced a recess A, into which a chase B, is inserted, the said chase carrying one or more lines of type B', and this chase is held inthe recess at the forward end of the bed plate by means of the turn-button B2. Just to the rear of the recess A-, is a circular recess A2, in which fits the inking disk C, having an integral shaft C', which extends through the opening A3, reduced in the bed-plate, and carries a ratc iet-wheei D, u on the lower end thereof, the purpose of w ich wili appear The bed-plate is cut away u on opposite sides as siicwn at A4, prcvidin r ibn git-udinal guidewr each side, and iding upon the bedpia these guideways is the frame E, having n. e.. projecting handles E', which are gras ed y the operator and the-frame E, move hack and forth upon the bed-plate for the purpose of o )erating the pencil feeding and printing mechanisms.

The frame E, has an arm F, attached to one side thereof, and which embraces one edge of the bed-plate and extends thereunder as shown in dotted lines in Figs. 1 and 2, and the inner end of this arm'is provided with a springy paWlG, which is adapted to engage the ratchet-wheel D, during each reciprocation of the frame E, and this engagement of the pawl withl the ratehet-wheelserves to turnthe inking disk C, step by step, and thereby uniformly distribute the ink to the inking roller H, journaled in slots H', produced in the sides of the frame E, and normally held in engagement with either the inking disk or type, by means of springs H2, which are connected to the opposite ends of the platen and bear at their free ends upon the journals of the ink roller. It will be noticed that the rolleris made the full width of the machine and the inking disk substantially'the same width as the length of the roller., thereby permitting a maximumlength of line to be printed upon the pencil. The platen I, is connected to the forward ends of the side members of the frame E, and the saidside members are undercut as shown at E2, beneath the platen I, the purpose of this undercut being to permit a pencil to be dro )pcd beneath the platen and caused by said platen to travel over'the face of ,the type during the forward movement of the frame as hereinafter more fully explained. The platen I, is covered upon the under side by means of a piece of fabric K, the ends of said fabric beingfconnected to winding shafts K', passin f through the sides of the' frame and secure y connected to the top of the platen bv means of clip-plates K2, secured by screws K3, said screws and plates being loosened when it is desired to unwind a portion of the fabric from one shaft and `wind it upon the other, for the purpose of presenting a clean portion of fabric. The fabric covering of the platen, not only serves as a cushion, but it also prevents the slipping of the pencil and insures an even rotation of the pencil 'as it )asses along under the platen and over the eines of type. l

ylhe pencils L, are carried in a hopper atl t forward ends of the frame and are dropped in a horizontal position one at a time, the pencil being dro ped just in advance of the platen when t e frame reaches the limit of itsrearward movement, andupon the forward movement of the frame the IOO IIO

pencil is caused to travel beneath the platen and over the line' of type and in this manner receives the imprint upon the curved surface of the pencil, 1t being understood that my machine is intended to be used for printing round encils only.

The hopper comprises the adjustable sideplates M, having slotted arms M', which slotted arms M', are connected to the rear inclined guide-bars N, said guide-bars being connecte( at their lower ends to a forward cross bar O, which is attached to and con.- nects the forward ends of the side members of the frame E. This front bar O, projects laterally upon opposite sides of the machine, and is bent back upon itself at O, providing feedways directly beneath the ends of the side lates M, of the hopper and connected to the ee ends of the return portion are the front inclined guide-bars P, said bars N. and P, serving to feed the pencils in proper order. Said bars converging toward each other as most clearly shown and the lower ends thereof extend in parallel relation as shown at N, and P', and are spaced apart a sufficient distance tov permit yone pencil and one pencil only, to pass down through. By this it is meant that the pencils in passing down' between the contracting or converging ends of the guide-bars, rest one above the other as most clearly shown in Fig. 2.

For the-purpose of feeding the pencils from the hopper, one at a time, I employ the u er Vcut-ofi` rods R, and the lower cut-off ro( s the forward ends of said rods working through openings produced in the front bar 0,-ad1acent the ide-bars N, and O, and the rear ends of t ese rods are connected'v to the oppositely arranged arms RZ-and R3, carried b connecte thereto serving to hold t e rockshaft in such position that the lower cutofi` rod R', will normally extend across the bottom of the hopper and hold the bottom pencil from dropping. When the frame is pushed back to the vfull limit, a tripping arm carried b the rock-shaft R4, en ages a stop T, rojecting upwardly from the bedplate an such movement forces the forward end of the up er cut-ofi` rods R, between the bottom penci and the one next above and simultaneously-draws the bottom rods R', rearwardly, so as to drop the bottom pencil directly in advance of theplaten and the rear of the chase.

In Fig. 2, I have shown in full lines the positions of the various parts when the frame and hop er have reached the limit of their rearwar( 'movements and the bottom pencil has just been dropped. Upon .the return movement of the frame, the positions of the cut-off rods are reversed, and the pencil is caused to travel beneath the face of the type and beyond t e forward end the rock-shaft R, the s ring S,`

laten over the of the bed plate, and in this manner is discharged from the machine. During this and the return movement the type are thoroughly inked and ready to make another imprint upon the next encil which is dropped when the frame reac es the end of this rear movement.

It will thus be -seen that I provide an exceedingly cheap, simple and efficient construction of hand-o erative pencil printing machine, capable oi) printing one or more lines upon the pencil at one tlme.

H avm thus fully described my invention, what I cPaim as new and desire to secure by Letters Patent is 1. In a pencil rinting machlne, the combination with a Ibed-plate provided with a chase and an inkin disk, of a frame movable upon the bedl(iate and carrying a hopper, a platen also carried by the frame having its under side covered with fabric, and means for feeding the pencils from the hopper, one at a time, and causing them to travel over the chase and under s'aid platen,

g as set forth.

2. In a pencil rintmg machine,vthe combination with tfie bed-plate carryin the chase and ink-disk, a reci rocating ame carrying a platen,l inking ro ler, pencil ho per, cut-off rods, and means for operating t e cut-ofi' rods as specified.

3. In a pencil printing machine, 'the combination with the bed-plate carrying a chase, of a reciprocating frame, a platen carried by the frame winding shafts mounted on said platen carrying a stri of fabric extending over the under side o said platen, the forward ends ofthe frame being undercut as specified. l

4. In a pencil rinting machine, the combination with the ed-plate, having the chase, inking disk,I and stop, of the reciprocating frame, the inking roll, the platen, the hopper, comprising the converging guide-bars and adjustable endv plates, the upper and lower cut-off rods, the rock shaft to which the 'rods are connected, the-spring connected to said shaft, the tripping arm connected also to the shaft, the operating handles vconnected to the frame, and meansfor rotating the ink disk, substantially as described.
